COMBINATION-TOOL.

To all whom it'may concern: 7

Be it known that I, GHRESTEN T. MAosEN, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Combination-Tools, of which the following is a specification.

This invention relates to combination tools; and has for its object to provide a novel and advantageous foldable tool particularlyadapted for use by carpenters in fitting doors, window sashes, etc.

In carrying out the invention a substantial handle, similar to that of a pocket knife, is fitted at one end with a foldable blade, the end of which is shaped to form a screw driver. At the other end a foldable socket is provided to receive a scratchawl or any of a number of similar tools. The back of the tool is fitted at each end with a foldable scribing point, either of which may be used in connection with one of a pair of slidably adjustable stops on the. back of the handle to mark lines parallel to the edges of the material to be marked.

One form which the invention may assume is described in the following specification and shown in the accompanying drawings, in which V Figure 1 is a side elevation of the tool, with all of the parts folded into the handle.

Fig. 2 is a longitudinal, sectional View on line 22 of Fig. 3.

Fig. 3 is a plan view of the back of the tool.

Fig. 4 is a cross-sectional View on line 44 of Fig. 1.

Fig. 5 is a similar view on line 55 of Fig. 1.

Fig. 6 is a cross-sectional View on line 66 of Fig. 2.

The handle of the tool is indicated generally at A. This handle, as shown in Fig. 4, is similar to that of an ordinary pocket knife, having two sides B and C and a back D. Each end of the handle A is fitted with a tool, as shown at 10 and 11. These tools are pivotally mounted at 12 and 13 between the ends of the sides B and C and are folda'ble into the handle A, as shown in dotted lines in Fig. 2. The tool shown at 10 is designed to serve as a screw driver, having a square tapered end 16. It may also be centrally sharpened, as shown at 16 (Figs. 2 and 4.), to form an ordinary knife blade. The foldable member 11 is open-ended and Specification of Letters Patent.

fitted with a. set-screw 17 (Fig. 6). This construction is designed to permit the use of a variety of tools in the socket thus provided. In the drawings a scratch awl 18 is fitted in this socket.

A pair of scribing points 19 is pivotally mounted at each endof the handle A, between the sides B and C. A portion of the back D is'cut away at each end to permit the points 19 to fold down flush with the outer surface of the back D, as shown in Fig. 1 Thesides B and C are cut away at the same place (Fig. 1) to give access to the scribing points when it is desired to turn them up into operative position, as shown in Fig. 2. In this position the points are held against further movement about their pivots by means of stops 21 formed by the ends of the handle A.

Both the scribing points 19 and the members 10 and 11 are held in. extended or folded position by meansof two parallel springs 22 and'23, centrally mounted interiorly of the handle A and'extendin'g from end to end thereof. A cross-piece 15, extending from side B to side C, forms a point of support for the springs 22 and 23, which, as shown in Figs. 2 and 5, are fastened thereto by rivets 15 or other suitable means extending through the springs and through a separat ing block 24 placed between them at that point. As shown in Fig. 1, the ends of the U-shaped cross-piece 15, may be secured to the sides of the handle by rivets 15". With this arrangement the ends of the spring 22 press the heels of the points 19, while the corresponding ends 1a of the spring 23 press the heels of the members 10 and 11. All the pivotally mounted members are thus held in either extended or folded position by means of the internal springs.

The adjustable stops provided to cooperate with the fold-able scribing points 19 consist of a pair of bolts 25 fitted with nuts 26 and slidably mounted in a slot 27 in the back D of the handle A. The bolts 25 have a square shank, as shown at 28, to prevent them from turning when the nuts 26 are screwed or unscrewed.

It will readily be seen that with this construetion a stop can be provided at any point to cooperate with either of the scribing members by moving one of the bolts 25 to the desired point and tightening the nut 26.

' A tool of the character described is particularly useful in hanging doors and in interior finish work in general. For instance,

in hanging doors one of the scribing tools may be set to mark the position for the hinges on the door and the other to mark the position for the hinges on the door jamb. One edge of the hinge being held on the line thus made the remainder of its outline may be marked by using the awl 18, after which it may be screwed in place with the screw driver.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A handle of the character described, including parallel sides and a slotted back with spaces at each end between the sides, pivoted blocks with fiat rectangular sides and scribing points projectable through the spaces at the ends of the back, centrally fixed springs extending outwardly between the handle ends, said spring ends pressing against the flat sides of the blocks, and slidable stops on the handle back cooperating with the scribing points.

2. A tool having a handle formed with spaced parallel sides, said sides having alined apertures therein, a cross-piece eX- tending through said alined apertures in said sides and having its ends turned at right angles and engaged with the outer faces of said sides, a spring afiixed to said crosspiece, and a pivoted tool member engaged with said spring and movable to lie between and also outwardly beyond the sides.

3. A tool having a handle provided with spaced sides and an end wall, a spring between the sides, and a pivoted tool having a side thereof formed to engage said end wall to hold the tool operative and at right angles to the longitudinal. axis of the holder, and having an end which when the tool is in operative position is engaged by the spring and which when the tool is inoperative is engaged by the said end wall of the handle.

a. A tool having a handle provided with spaced sides and a slotted back, a substantially U-shaped cross piece extending across the space between the sides and spaced from the back and having its ends engaged with the outer faces of the sides, a spring connected to the cross-piece, a stop operating in the slot and in said space between the crosspiece and back, and a pivoted tool tensioned by the spring and cooperating with the stop.

A tool having a handle formed with end walls adjacent its back and with spaced slots in said back, a pivoted tool in one slot engageable with one of said end walls in operative position and being disposed between said end wall and the inner end of said slot in inoperative position, and a stop slidable in the other slot and cooperating with the tool.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
